[ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX] - page 515.

When I'm mining with latest CCminer release (and all previous...) on my EVGA 750TI SC, its core frequency randomly drops to around 500Mhz, and nothing, except for a reboot, fixes this. It does this for every algo, after about half an hour. After that, I can't get any accepted going through. It's mining keccak flawlessly, so I'm leaving it at a MAX pool. But I love how its hashrate for, ea, quark is better than an R9 290 Tongue

EDIT: No problems at all for my gtx760, no other cards ATM (Gigabyte 750TI is in shipment Tongue

)

I have a similar problem with my EVGA 750TI SC as well, but it only happens with quark as far as I've noticed - all of a sudden, low hash/clock, and no accepted shares.

I don't reboot though. If you're on windows, just go into device manager, disable, then re-enable that card. This reloads the drivers, and re-initializes the card. Should work for you as well.

Annoying as heck, though.

It means your overclock is too high. the 500MHz is some failsafe feature where the card goes after a crash

Mine does this even with stock clocks, and slightly underclocked. No problems with anything else, and can usually run +65/+300

on a riser or directly in a pcie slot ?
the "disabling"/"enabling" never worked for me...

At stock OC, I got this too. Will try it again at stock, underclock if that didn't work.
I'm used to a complete 2min freeze-up & driver crash when I OC too high on Cudaminer, but this is possible too?

Disabling/enabling didn't work for me Sad

Only reboots work.
But yeah, it's pretty possible it's a bug in CC's quark. I hope it doesn't, I'm owning QRK ATM Tongue

Never felt so good with my puny nvidia cards.

I know the feeling! Wink

I had the same with bitquark, but only the second card. The problem stopped, when I closed Evga Precision. Weird.

Why are people so excited about BitQuark? Currently mining it with 750Ti is not worth the effort :!

I was wondering the same. Unless my tool is completely wrong, this is the most unprofitable coin in a long time:

Current Diff = 1275
My Hashrate = 14MH (5x750Ti, I actually took some numbers from this thread and made a low estimation with 2800khash per card)
coins/day = 0.5519
current price = 0.00001100
profit/day = 0.00000607 BTC

if I remember correctly, diff was around 70-80 before I published ccMiner v0.9, lol Wink

I was finding blocks every minute.

I think you tool might be off. With 14 MH/s you should find several blocks per hour.

Christian

As I posted with the donation I made to those who helped me get it running yesterday, I mined 38 blocks in 6 hours, so nearly 100 coins. That would average almost 400 coins a day right now, so something is your calcs are off (and I was mining with 6x 750 ti).

Which still isn't spectacular, but it isn't terrible at all right now.

Well, I checked a pool, and I saw that they get a few blocks per hours with ~17MH at the current difficulty. I just don't understand why my calculation is wrong ^^ I check nearly every other coin against public/coin specific calculators, and the result was the same. So, either the chance that a submitted share is accepted is better than 2^32 or...well...I don't have another explanation ^^

06/19/11 17:51 Bought BTC 259684.77 for 0.0101

I have a quick compiling question for the devs. From what I've gathered, I should be working with cuda 5.5 and VS 2010. I currently downloaded cuda 6 and VS 2013 (express). I haven't gotten started with it all yet because I've been so busy, but will I be able to use this at all? I totally understand how different things can become on newer software versions, and I'm willing to spend the effort to figure it all out, but I also don't want to waste my time if it's just impossible. I'm pretty new to programming, but I tend to be self sufficient on this kind of stuff so I welcome the challenge if it's doable. I'm also extremely OCD about software updates and always go for the newer versions if they work.

Thanks for any information you can provide, and thanks again for your hard work on this project and the generosity to share it all with us

Set -q and it will only show when you find a block or submit a share. So solomining you will only successful blocks

Well, that's wise, but now I cannot see my hashing speed.

That a choice you have to made.
However, the speed never change (from my experience), so once you know what is your speed for your cards, there isn't much point to continue to display it.
I think using ">> log" (or something like that) should give you the full logfile (in linux playing with tail and grep could help you to achieve what you want... but in windows I am totally clueless)

@nomad1109: Thanks for the BTQ, you quadrupled my balance.

[Your startup command] 2>&1 >> logfile.txt

That will redirect standard output (1) and error output (2) to a single logfile where it will append to the end of the file rather than overwrite what is there.

You won't see anything on the screen anymore, but you will log all the output to a file you can search through later.

There is a way to put the output to both, but it can require some more setup or specific needs on your end...

[Your startup command] 2>&1 | tee logfile.txt

Hope that helps.

Apparently mjollnir would not work (I wasn't able to check that... diffilculty too high), supposedly cpu only (with latest ccminer in its github) with ultrahigh hashrate at start. (dev has a large miner)
No point in mining this, but who knows... Grin

both bigjme and djm34 was right. But try this one maybe this will help you bro,

remove the -q then add " 2>> logfile.txt " to your .bat

You guys get so excited with new algo that can probably mine a single coin (with very little profit). I can imagine many people will become insane once x11 is out because this single mining algo (combine into 1 single algo) open over 10 coins and more are created each week.

huh, quark alone will mine about a dozen of coins.

But X11 is being worked on actively.
